  Derived from the live /.well-known/ documents served on trycreate.co plus the
  observed behaviour of the UCP MCP endpoint. There is no OpenAPI to derive
  securitySchemes from; every statement below was read off a document that
  returned 200 on 2026-08-11.

    POST tools/list with no Authorization header returned 200 and the full
    13-tool manifest. No WWW-Authenticate challenge, no invalid_token error.

    description: >-
      Every tool requires an agent profile URI in meta. This is agent
      self-identification for UCP discovery, not authentication — it is not
      verified against any credential.

gaps:
- >-
  The authorization server is Shopify's, not Create Wellness's — a buyer
  authenticating against this store is authenticating against
  shopify.com/authentication/61192044732. There is no brand-operated IdP.
- >-
  No published API key programme, no partner/developer credential, and no
  developer documentation of any kind on the brand host. The only auth
  documentation is the platform-generated llms.txt.
